The Illawarra Grammar School was founded in 1959 by Bishop Gordon Begbie and dedicated parents. On its opening day, 3 February 1959, the first headmaster, Rev. Richard Bosanquet and two staff, welcomed 28 students into the school. In 1975, the school became co-educational when it amalgamated with SCEGGS 'Gleniffer Brae'.[1] In 2009 TIGS celebrated the Golden Jubilee of its founding.[2]

In 2012, TIGS became an International Baccalaureate World School, implementing the Primary Years Program (PYP).[3] In 2016, the school became accredited for the Middle Years Program (MYP) and the IB Diploma Programme (DP).[4] Students in Year 11 are given a choice between the NSW HSC program and the DP program.[5] At the end of 2018, TIGS announced the appointment of the eighth Head of School, Judi Nealy as the successor for long-serving Headmaster, Stephen Kinsella.[6]
